Also I do not wish to be limited in my claims because oit my failure at this time to appreciate the full usefulness of my invention.y as I intend fit to be -used in the future in any manner that may turn out to be econoinical and convenient, and that niere niechai'iical' changes necessary to adapt it to future uses be fuly included in the scope ot my invention.
